I've been a little scared as how the screen turns off during a phone call. Reading on these forums I see that its natural via a sensor. Well, now its turned off completely during a call, I do not know if the phone call is still being timed and the screen pulses with a dim light like its trying to do something but, will neither turn on nor off? It was fully charged this morning? Help! I was afraid this was going to happen!? Is my droid dead??
